1. Vacuum Tube Lifters Basic Overview

2. Vacuum Lifting 1Two types of ‘vacuum lifting’ exist Where vacuum is generated to apply a grip using suction pads. The lift is usually provided by other means e.g. a PneuLift using compressed air generated venturi vacuum. 2Two types of ‘vacuum lifting’ exist A similar concept, but here vacuum is used not only to generate grip, but also provides the power for lifting. This is known as ‘vacuum tube lifting’, a popular, easy to use and efficient handling solution

4. Typical System Layout Crane Vertical support pillar c/w swing jib This is the most common style of crane employed for workstation handling. Variations include; wall mounted jib/stanchion mounted jib and alternative jib types such as inverted and knuckle (or articulated) Bridge cranes are also commonly used.

5. Typical System Layout Vacuum Pump/Relief Valve Direct Drive No Maintenance Low Noise Levels - 71dB(A) at 3 feet High Flow 230v/460v pump runs at +/- 10% variance in voltage. Will not run on 208 volts!! Relief valve fitted to protect pump for non porous loads.

6. Typical System Layout Filters CF130 - Low Dust Levels CF220 - Medium Dust Levels BF10925 - High Dust Levels 70% efficient at 0.17microns

7. Typical System Layout Lift Tubes Diameters from 100 to 250mm Neoprene & Polyester 2 ply construction is very durable Standard has exposed wire helix - suitable for wipe clean only Upgrade for Food/Pharmaceutical has coated helix Combine tubes to increase capacity Capacity of SLTA/MLTA is given to bottom tube manifold/can. All other items must be added i.e. control handle, end effector and product load

8. Tube Assembly 360 o Rotary Safety Plate Support Rope Vacuum SLTA - Single Lift Tube Assembly As vacuum travels through the system the safety plate raises, allowing air flow If vacuum flow is interrupted for any reason e.g. pump failure, the safety plate closes and seals the remaining vacuum in the tube and end effector Palamatic’s safety ratios ensure that, as vacuum levels drop, the load is secure in position until it reaches floor level (or close proximity) This ensures the operators’ safety The weight of the control handle and end effector is secured by the support rope when power is off
